Bash and Python script to kill Amazon EC2 instances based on elapsed time since launch. Allows for warnings and dry runs. Use with care.
TERMINATE EXECUTABLE NEEDS TO BE UNCOMMENTED IN THE SCRIPTS
The script killer3.py is a python 3 and boto3-based version of the killer.py
script. This version adds the ability to specify an AWS CLI profile to use for
authentication. Also the script requires that you specify the -y or --yes
argument to terminate instances. Otherwise it does not make any changes. Like
the previous script, the actual line to terminate the instance is commented
out. This is a dangerous script! Use wisely and at your own risk.
usage: killer3.py [-h] [-t TERMINATE] [-w WARN] [-p PROFILE] [-r REGION] [-y]
optional arguments:
-h, --help show this help message and exit
-t TERMINATE, --terminate TERMINATE
Terminate instances older than this many hours
(default 72)
-w WARN, --warn WARN Warn for any instances older than this many hours
(default 36)
-p PROFILE, --profile PROFILE
The awscli profile name you wish to use (default
'default')
-r REGION, --region REGION
The AWS region you want to interact with (default us-
east-1)
-y, --yes Terminate instances (default is 'do nothing')
